TAP Fon BARnELs.

Application led March 17, 1924. Serial No. 699,831.

To all whom t .may con-cern; Y

Be it known Vthat I, HENRY G. OItnrnnr, a citizen of the United States,residing at Joliet, in the county of Will and State of Illinois, haveinvented certain new and useful Improvements in Taps for- Barrels, ofwhich the following is a specification.`

My invention relates lto devices used for withdrawing liquids from kegs,Ibarrels and the-like and particularly to means adapted for use inwithdraw-ing liquids by pressure from such containers. v An object oftheinventionis to provide ,adevice vwhichmay be quickly and convenientlyinstalled without the use of tools and which shall avoid the necessity.for any speused. Y -v f In the dispensing of certain liquids underpressure 'it "is necessary to employ a tap having the double function ofan inlet and an outlet, the inlet being for the fluid cial implements ofthesort now commonly under pressure and the outlet for the liquid.

In the device here' disclosed I provide means whereby the frame maybesecurely attached to' the head ofthe keg or barrel, projections beingprovided intended to nnderlie the chime of the keg. Mounted on vtheframe is a clamping device'adapted to adjust itself to inequalities` inthe surface of the head and to be adjusted to a posit-ion over theopening in the head'.v When properly adjusted and Vclamped'i'in positionthe closure or bung is displaced by thetube or conduit through which theliquid is withdrawn. The space around theconduit provides access for thefluid under pressure utilized for displacing the liquid.

{The advantages described together with others not specificallymentioned will be rmade apparentfrom the accompanying description. l

The'invention will bev morereadily understood by reference to theaccompanying drawings, in whichvFigure 1 is a longitudinal verticalsection Y through. a device constructed yin accordance with myinvention, the device being shown as applied to a keg;

Fig. 2 isa plan view `of device;

` Fig. 3 is a vertical sectional view. on the line 3-3 of Fig. 1;

Fig. 4 is a' sectionalview onxline 4 4 of Fig. 1; and

Fig. 5 isa sectional view on line 5-5 vfrom the portion 12 of the frameis a diagonally disposed projection 14, the lower terminal portions ofwhich are of arcuate form and may be serrated, as shown. .These portionslare intended to underlie the chime 15 of a keg as shownin Fig. 1..V fY.

The portion 10of the frame provides a pair of parallel. guides 16 onwhich a slide 17 is mounted. The upper surfacefof "the slide has a rack18 formed thereon, while the outer extremity of the slide has anarcuatediagonally arranged portion 19 shapedv to underlie a diametricallyopposite portion of the chime 15. Engaging the teeth of the Y rack is apivoted d0g 20 arrangedin a diagonal position within the reces'srllheretofore referred to. The dog is pivoted to the lower end of a screw21 adapted to be actuated by a hand wheel 22. A detail of the form i ofconnection between the dog and screw .is shown in Fig. 4. From that viewit will be seen that the screw is provided with. a head 23 which engagesin an undercut recess in the dog, and that because oflimitedlateralmovement of the dog within Vthe recess, the parts cannot becomeseparated until the screw is .advanced to a point outside of the limitsof the recess. The pivot action. is secured because of the play in theconnection. It will be noted that the thrust ofthe screw through the dogon the slide is applied in the direction of outward or radial movementof thel slide. It will also be noted that the slide may be extended,that is, moved outwardly radially withoutl interference 'from the dog. vi

In view of the fact that the clamping force is secured by reason ofexpansive pressure applied to the staves of the keg, such vforce shouldbe limited to avoid bursting of the barrel by the application of toovgreatv force to the screw. 'To that end I have-'provided means limitingthe travel ofthe dog tion close to the wall 24. lhereafter when vthescrew is actuated the dog will travel relative to the wall or stop 24-and will contact the same after traveling a relatively short distance,thus preventing any further travel under the action ot' the screw. If atthis time the device is not sufficiently tightly held, it is necessaryto retract the screw and engage a tooth of the rack to the rear of theone formerly engaged. It the pressure theretotore exerted tending` toburst the keg has been considerable, the parts will contract and returnthe slide to a position where it is impossible to engage another tooth.'Thus I provide means pre- VVenting the possibility of bursting t-he kegor barrel by non-intelligent operation of the device.

The means employed for clamping the discharge conduit in positionlcomprise a tubular member 25 having a head 26at its lower end which maybe faced with rubber 27 if desired. Connected to the tubular portion 25is a member similar to an angle cock comprising a body portion 28 and alateral tubular portion 29. Surrounding the portion 25 is an externallythreaded sleeve 30 freely rotatable but held against longitudinalmovement, by engagement at its respective ends with suitable stops. Atthe upper end the sleeve has projections 31 adapted as hand holds. Thethreaded sleeve engages with an interiorly threaded nut 32 havingguideways at its sides, the top and bottom wallsy 33-34 respectively ofthe guideways, being horizontally curved or arcuate as indicated at 33,34 in `Fig. 1. These guideways, one being provided at projections 31.

each side of the nut, engage with guides 35 constitutingpart of theportion 12 of the frame and defining the sides of the recess 13 `formedtherein. The curvature of the lsides of the guideways is to permit o'any necessary oscillation of the head 26 about the nut as a center toenable it to accommodate itself to inequalities inthe surface of thehead 36 of the keg. The guideway likewise permits of required radialmovement of the conduit as a whole to enable it to be adjusted to aposition directly over the opening 37 in the head. Angular adjustment tothe required position is secured by suitably positioning the lateralclamping device.

The vertical clamping action is secured by rotatingT the sleeve underthe action of the The employment of the rubber 'face for the disc 26insures a tight t between the head and the thrust element.

Mounted within the longitudinal aperture in the parts 25-28 is a tubularelement 38 which may be connectedby a hose or otherwise, to the point ofwithdrawal of the liquid within the keg. In orderto insure a tight jointaround the tubular member, I provide packing material and a gland nut 39having lateral projections t() for hand operation. lVhen installing thedevice and assuming that the frame has been clamped in position with thethrust device over the opening 37 in the head, force is applied to thetubular member 38 to dislodge the cork or plug l1 in the opening, thecork being 'forced downwardly into the keg. The tubular member is thenprojected to the bottom oi the container in the usual manner and thejoint at the upper end made tight by the gland nut.

It will be noted that a space is provided around the exterior of thetubular member 38, and this space is utilized for the admission of fluidunder pressure. Such fluid is supplied through the nipple 42 connectedto a suitable source of supply.

The device as described may be fpiicklyl operation serves to place thethrust memberVV 26 directly over the opening in thevhead and to clamp itin position. In the next 'operation the tubular member 38 is employed todisplace the cork from the opening and after tightening the gland nut,the device is ready for use. It may be employed repeatedly without lossof liquid or injury to the barrel; it avoids the necessity for usingiron ferrules or locking devices and eliminates the necessity orchangingthe pressure hose as is customary in the devices at present used. f

Obviously the construction is capable of much modification and Ido notwish to be limited except as indicated in the appended claims.
